Part # for RS6+ springs?

[Solo607]

Anyone know the Audi (Europe) part number for the springs from the rs6+?

[skiwi]

there were no special springs for the rs6+.

if you want "heavy duty springs", you need:

4b3 411 105j - front
4b3 511 115r - rear

those are for the saloon, the avant is different...

these spring were options for all rs6's....

Thank for the info. But I had heard that the RS6+ had slightly different springs, which lowered the car about another 10mm over the stock rs6. Ultimately I am trying find a suspension setup that will keep the DRC, as mine is fully functioning, while making the car handle a little better in corners. I had heard about mtm's spring perch, that keep all the stock setup, but still lowered the car roughly 10-15mm. But I can find no trace of it anywhere on the web, except a few quotes in other threads. So what are the heavy duty springs, or do you have any other suggestions?

Cheers.

no, the springs are weight graded. normal weight is option: pr-0jm (class 12) - although there are provisions for class 10 and 11 springs (speaking of front only here). there is a single "heavy duty" option, only specified for weight class 12, which is the number you have. this is specified by option pr-2me

i also meant to say that pr-2me also includes heavy duty shocks (again, not unique to the rs6+)....
